Design and Fabrication of Hydrazine Storability Test Tanks

Abstract

This report summarizes the work performed in designing, fabricating, and testing small-scale storable propellant tanks. The design incorporates full- scale missile tank features and typical weld stresses. Fabrication and test procedures are based on simulated production tooling and on actual procedures used in the manufacture of production tankage. The tank designs are based on seven different alloys. Five tanks were produced from each alloy. The alloys were: 2014-T6 aluminum alloy; 2021-T6 aluminum alloy; 2219-T-6 aluminum alloy; 17-7PH corrosion resistant steel; A-286 corrosion-resistant steel; AM-350 corrosion-resistant steel; and 6Al-4V titanium alloy. The tanks will be filled with N2H4 at the Rocket Propulsion Laboratory and stored in the RPL Storability Test facility. Tanks will not require passivation at RPL since they have been given a special accelerated hydrazine storability test. This process includes passivation.
